.4 Claims. (CI. -12) This invention relates to safety razors 'and more particularly to safety razors of the type having a foldable or collapsible handle which serves also as a container or casing of a shape suitable to display advertising matter, and which may be manufactured cheaply enough to be sold at a nominal price or given away as an advertisement and it is an object of this invention to provide an improved razor of the type.

described in which the flexible material forming the casing or handle is creased or scored so as to fold in a manner forming a substantially rigid handle when in use without materially lessening the facility with which it folds in order to form the container or casing when not in use. It is also an object of this invention to provide an improved blade holder which secures the blade in proper position for use.

As shown in the drawings a safety razor con-- structed in accordance with this invention coinprises a single-edged-blade 1 which may be ofv or creases 22 diverge from the ends of the slot edges of the sheet 3. a

the openings 16, the ends of the tomes being sition and a 'sheet 3 of flexible material, such as cardboard or fiber-board, which is somewhat more flexible than the cardboards commonly used in paper boxes and which is suitably treated, as with paraflin, in order to render the cardboard. more resistant to moisture, if desired. The blade holder 2 may be formed from sheet. metal and has the usual guard portion 4,; clips 6 which arestamped out of the body 5 of the blade holder and aid in positioning the blade, 10

'10 which has the tongues 12 struck out therefrom. The tongues 8 and 12 engage with an end 15 of the sheet3 to secure the sheet to the blade holder. The blade holder is alsoprovided with a. lug or boss 14 which prolecm upwardly from the blade holder 2 to engage in an opening in the blade 1 and prevent removal of the blade from the holder. I

As shown in Figs. 7, 8'and 9 the sheet 3 is provided with perforations 16 to receive the tongues 8 and 12 and is scored or creased so as to cause the sheet to fold in a predetermined way when used as a handle. As shown in Fig. '7, the scorings 18 may be parallel, extending longitudinally of the sheet adjacent the center thereof and ending at parallel slots 20 and 21 which extend transversely of the sheet. From the ends of the slot 20 extend the scores or creases 22 which diverge to the side edges of the sheet 3 slot 20 to the slot 21', the slot 21 in this case being of greater length than the slot 21. Scores 20 to the side edges of the sheet while the creases 23 diverge from the ends of slot 21 to the end of the sheet. In the modification shown in Figure 9 there is provided a central longitudinally extending score. or crease 18a and diverging side creases 18b, all 'of"the ;scores or creases extending from slot 20'to the far end-of the sheet 8. Diverging scores or creases 22 extend from the ends of the slot 20 to the side When assembled, .the blade holder 2 is secured 'to the sheet 3 by means ofthe tongues 8 and 12,

tongue 8 passing through the opening adjacent the slot 20, while the tongues 12 extend through bent down as shown in Figs. 2 and 5. The tongues hold the end of the sheet 3 bent about the curved portion 10 of the blade holder with an edge portion of the sheet 3 projecting partly over the blade 1 and forming a flap with which the opposite edge of the sheet may be engaged. When the razor is to be used sheet 3-is extended as shown in Figures 1 and 2 and the side portions of the sheet beyond the scores or creases 18 are engaged by the hand of the user, causing the sheet 3 tofold along the creases 22, 18 and 23. As shown in Figs. 10 to 13, the modification shown in Figure 7 will, under these conditions, provide a handle having a substantially fiat ion-t gitudinally extending center portion included between the slots 20 and 21 and the parallel longitudinally extending creases 18, while the side portions 19 of the sheet outside of the creases 18 form longitudinally extending flanges. The portion 1800f the sheet comprised between the creases 18 provides stiffness for the handle against lateral bending while the side portions 19 provide stifiness against bending in a plane perpendicular to the plane of the portion 180 so that the sheet, when folded, gives a rigid handle of substantially a hollow beam shape, with the portion 180 as the web.

Figures 14 to 17 show that the modification of Figure 8 assumes substantially the same shape as that of the modification of Figure 7 when folded as a handle except that the portion 180' comprised between the scores or creases l8 tapers towards the blade holder, but as in the previous modification, this portion'provides stifiness against lateral bending and the side portions 19' provide stifiness in a direction perpendicular to the plane of the portion 180.

In the modification shown in Figure 9 the portions 18012. of the sheet comprised between the side creases or scores 1% and the center crease 18a taper and are inclined to the central score or crease 18a, but in' this modification, as in the others, the position-of the portions 180a pro vides stifiness against later bending and the sideportions 19a provide stiffness in a direction substantially perpendicular to the plane of the portions 180a.

In each of the modifications the slot 20 at the blade holder end of the sheet 3 and the slot 21 or 21' at the other end of the sheet in the modifications shown in Figures 7 and 8, frees the ends of the portions 180, 180 and 180a oi the sheet between the scores or'creases 18, 18' or 18b respectively and prevents the distortion of this portion bystresses which, if transmitted thereto, would tend to distort the shape of these portions and to lessen their resistance to lateral bending;

The scores or creases 22 extend the portions 19, 19' and 19a beneath the portions secured to the bladeholder 2 so as to support these portions when the razor is in use and the divergence of these scores gives a tapering of the side portions which causes the blade holder 2 to be inclined to the handle at the most eflective angle for use of the razor.

No scoring or creasing of the sheet 3 is necessary in order that it may be folded into the position shown in Fig. 3 and the scores or creases described in no way-afiect this folding of the sheet 3 once the portion thereof whichforms the handle is restored to a flat condition as shown in Figs. '7, 8 and 9.-

What is claimed is l l. A safety razor including a sheet of flexible material having a told at one end forming a blade receiving pocket and the remainder of said sheet-having spaced scores or creases extending longitudinally thereof to shape said sheet as a beam resisting lateral bending when folded along said scores or creases for use as a handle,

said sheet having means extending between said creases and defining part of an end of the beam.

2. A safety razor including a sheet of flexible material having a fold at one end to form a pocket receiving a blade and the remainder of said sheet'having spaced scores or creases extending longitudinally thereof to shape said sheet as a beam resisting lateral bending when folded along said creases for use as a handle and slots extending between said creases and separating parts of the ends of said beam from 7 said sheet. 7

3. A safety razor including a sheet of flexible material having a fold at one end to form a pocket receiving a blade and the remainder of said sheet having spaced scores or creases extending longitudinally thereof to shape said sheet as a beam resisting lateral bending when folded along said creases for use as a handle, a slot extending between said creases and separating part of an end of said beam from the sheet and creases along which the sheet tends to fold when in use as a handle diverging from the ends of said slot.

4. A safety razor including a sheet of flexible material having a fold at one end to form a pocket receiving a blade and having the remainder of said sheet form a handle, said handle having a central longitudinally extending crease and side creases spaced from said central crease, said side creases diverging toward the free end of said handle and with said central crease shaping said sheet as a beam resisting lateral bending when saidsheet is folded along said creases for use as ahandle.
